The Dynamical Implications of Multiple Stellar Formation Events in Galactic Globular Clusters
Abstract
Various Galactic globular clusters display abundance anomalies that affect the morphology of their color-magnitude diagrams. In this paper we consider the possibility of helium enhancement in the anomalous horizontal branch of NGC 2808. We examine the dynamics of a self-enrichment scenario in which an initial generation of stars with a top-heavy initial mass function enriches the interstellar medium with helium via the low-velocity ejecta of …
